The well-established \"Confusion-Assessment-Method-for-Intensive-Care-Unit\" (CAM-ICU) for diagnosing POD in intubated patients cannot make use of the feature 'disorientation', as this requires verbal communication. Other tools such as the 4AT test for disorientation but are not established in ICU settings. We therefore combined test-variables of the CAM-ICU (level of consciousness, fluctuating mental status and inattention) with verbal testing for disorientation to develop and enhance diagnostic accuracy of the \"Confusion Assessment Method for Intermediate Care Unit\" (CAM-IMC). In the present study we describe the development and the evaluation of the diagnostic accuracy of the CAM-IMC.</p><p><strong>Methods: </strong>We conducted a prospective cohort-study to develop and evaluate the diagnostic accuracy of the CAM-IMC and disorientation for diagnosing POD in non-intubated patients undergoing elective cardiac surgery. All patients were eligible during data collection period. Exclusion criteria were preexisting brain-organic disease, age < 50 years, preoperative intubation, and insufficient language skills. Patients were assessed for POD using the CAM-IMC as the index-test by two independent examiners over three postoperative days. Reference-testing was conducted by experienced reference-raters.

Area-Under-the-Receiver-Operating-Characteristic-Curve (AUROC; equivalent to c-statistic) for CAM-IMC with a cut-off at three points was 0.95 (CI-95%: 0.93-0.98).

Given an aging community with an increasing delirium risk, the CAM-IMC provides a highly structured assessment tool for POD. It enables early and accurate detection of delirium, which is critical for timely intervention and improved patient outcomes. The CAM-IMC appears to be a useful tool to be implemented in units for not-intubated patients and seems to be the perfect match where the CAM-ICU is already in use for monitoring POD.</p><p><strong>Trial registration: </strong>DRKS00026980 (German registry of clinical studies).</p>","PeriodicalId":9190,"journal":{"name":"BMC Anesthesiology","volume":"24 1","pages":"451"},"PeriodicalIF":2.3,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11639109/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142821774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated the analgesic effects of SNB in pediatric craniotomy patients by comparing preoperative versus postoperative administration.</p><p><strong>Methods: </strong>This randomized trial included 180 children (1-12 years) who underwent elective craniotomy and were assigned to the preoperative, postoperative, or nonblocking control group. The outcomes included cumulative sufentanil use, pain scores (1, 2, 4, 24, 48 h postoperation), rescue medicine utilization, postoperative complications (24, 48 h), and hospitalization length. The primary outcome was total sufentanil use within 24 h postsurgery.</p><p><strong>Results: </strong>Total sufentanil use (µg·kg^- 1) in the postoperative block group was significantly lower than that in the nonblocking control group at 1 h (P < 0.001, 95% CI [-0.024 to -0.006]), 2 h (P < 0.001, 95% CI [-0.054 to -0.020]), 4 h (P < 0.001, 95% CI [-0.089 to -0.032]), 24 h (P < 0.001, 95% CI [-0.192 to -0.047]), and 48 h (P = 0.010, 95% CI [-0.208 to -0.022]) postoperation. Additionally, sufentanil use in the preoperative block group was significantly lower than that in the nonblocking control group at 1 h (P = 0.004, 95% CI [-0.021 to -0.003]), 2 h (P < 0.001, 95% CI [-0.043 to -0.010]), and 4 h (P = 0.002, 95% CI [-0.069 to -0.013]). Within 24 h postoperation, the use of sufentanil in the postoperative block group was significantly lower than that in the preoperative block group (P = 0.014, 95% CI [-0.157 to -0.013]).</p><p><strong>Conclusion: </strong>Compared with preoperative SNB or nonblocking, postoperative SNB significantly reduces postoperative sufentanil use within 24 h for pediatric patients undergoing craniotomy, highlighting its potential as an effective analgesic intervention in this population.</p><p><strong>Trial registration: </strong>The trial was registered at the Chinese Clinical Trial Registry (ChiCTR1800017386) on 27/07/2018, under the title \"A study of scalp nerve block for neurosurgical analgesia in children with craniotomy.\"</p>","PeriodicalId":9190,"journal":{"name":"BMC Anesthesiology","volume":"24 1","pages":"441"},"PeriodicalIF":2.3,"publicationDate":"2024-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11603626/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142750022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
